East Renfrewshire Council told Glasgow Live an event with some of their schools had been cancelled due to exam pressures for older children.

They said it would be mostly first year pupils who would be able to attend and that the book was considered inappropriate for 12-year-olds. The book is aimed at children aged 13 and over. They insisted the council's schools are committed to equality.

"We have been in schools around the UK. They all have exams on and they said it was a nice break."

Some of John's fans felt the snub could have been due to the fact the book has a gay character.

There are also a number of potentially controversial issues examined in the book including teenage pregnancy, homelessness, and allusions to sexuality.

However, John is not letting the incident affect his relationship with his home city.

He said: "We didn't let it dampen our visit.

"I thoroughly enjoyed the two schools we went to in the Glasgow area."

Barrowman isn't scared to provoke debate. He gave Glasgow one of its most iconic moments during the Commonwealth Games Opening Ceremony in 2014 when he kissed another man in an unplanned moment during a dance routine.

And the move sparked discussion in other Commonwealth Countries where being gay is still considered socially unacceptable.

Barrowman said: "The Commonwealth Games thing wasn't done in a malicious way.

"That was normal to me.

"And it started a discussion in lots of other countries.

"We shouldn't be scared about it. It's who I am.

"It's 2016. If a man wants to kiss a man or a woman wants to kiss a woman, let them do it."

Barrowman's book Conjurer follows the story of 17-year-old Rémy Dupree Rush who is a Conjuror, a descendant of an ancient African bloodline that can change reality with music.

The authoris keen to hear what people think about it is and is urging the youngsters who bought copies at his signing event in Glasgow to review the story on Amazon.co.uk
